Baron Sandhurst, of Sandhurst in the County of Berkshire, is a title in the Peerage of the United Kingdom.^[1] It was created on 28 March 1871 for the soldier Sir William Mansfield, Commander-in-Chief of India between 1865 and 1870 and Commander-in-Chief of Ireland between 1870 and 1875. He was the grandson of Sir James Mansfield, Solicitor-General and Chief Justice of the Common Pleas. Lord Sandhurst's eldest son, the second Baron, was a Liberal politician and also served as Governor of Bombay. On 1 January 1917 he was created Viscount Sandhurst, of Sandhurst in the County of Berkshire, in the Peerage of the United Kingdom.^[2] However, he had no surviving male issue and on his death in 1921 the viscountcy became extinct. He was succeeded in the barony by his younger brother, the third Baron. As of 2021 the title is held by the latter's great-grandson, the sixth Baron, who succeeded his father in 2002. He is a barrister and judge and was elected to a hereditary-peers' seat in the House of Lords in 2021.
